The billionaire who gave $1.35 million to study the ability of transgender people to serve openly in the military has come out as transgender. Jennifer Natalya Pritzker announced in a memo to employees of the Pritzker Military Library and Tawani Enterprises, a private investment firm, that she had legally changed her name from James.

Pritzker, who is a cousin of Commerce Secretary Penny Pritzker, comes from a prominent Chicago family. Last month, the Tawani Foundation, which Jennifer Pritzker founded, gave the Palm Center a grant to study the possibility of including transgender troops in the military. The Palm Center had previously conducted many studies supporting the repeal of Don’t Ask, Don’t Tell.

As James, Pritzker, who is 61, served 11 years in active duty in the military, followed by 16 years in the National Guard. She is listed on Forbes‘ list of 1000 leading billionaires.
